The Solar@Sea II project is focussing on developing and deploying an offshore monitoring system and moored scaled basin tests; providing a functional design for the floater, the engineering and hardware for the mooring system and the installation strategy and guidelines; update the two existing floaters and deliver two new floaters; designing an appropriate antifouling strategy for the floaters at the North Sea, carry out exposure tests with suitable coatings and/or cleaning tools and monitoring biofouling growth on the exposed structure; research the durability of the PV modules; this will provide yield predictions as input for LCOE analysis; carry out structural modelling of the floaters, monitoring requirements and sensors for strain measurements on the floater and floater-PV interface; material tests for longevity and strength through accelerated lifetime laboratory tests. - installation and decommissioning of the offshore pilotRESULTS
The Solar@Sea III project will set the base needed for future large scale deployment of lightweight flexible floater types for offshore PV arrays. This pilot will reduce a number of knowledge gaps, develop and test new technologies needed to fully exploit this technology in offshore conditions and provide necessary parameters to refine LCOE calculations, needed to define business cases for future large scale deployments. The main results of this project are listed below: - Hydro-mechanic design tools for large flexible structures made suitable for offshore deployments - Shared mooring technology for floating PV arrays developed and tested - Performance of flexible floater technology assessed in offshore conditions - Innovative installation and decommissioning method for flexible floating PV arrays developed and tested - Monitoring biofouling development in offshore conditions and control strategy defined and tested. - Novel monitoring system with digital twin approach developed and applied - Yield and lifetime of flexible PV panels assessed for offshore deployments This knowledge will be disseminated in the form of peer-reviewed paper(s).PARTNERS
